What is the smallest part of this living thing?

4
COMPARING CELLS The size & shape of a cell relates to its function (job it does).

5
CELLS  There are two kinds of cells: Animal & Plant  Some organisms are unicellular (single-celled) and some organisms are multicellular (many cells).  All cells do three activities or things: 1. Bring materials into the cell. 2. Use the materials for life activities and processes. 3. Get rid of waste.

Nucleus DNA Mitochondria Vacuole Cytoplasm Ribosomes

8
NUCLEUS  Controls all cell activities  Contains the instructions for everything the cell does  These instructions are found on a material called DNA  Usually the largest organelle

9
CELL MEMBRANE  Protective layer around ALL cells  Controls what enters and leaves the cell  For cells with a cell wall, the cell membrane is on the inside of the cell wall  Allows water, gases (O 2 & CO 2 ), and materials into the cell & waste materials out of the cell.

10
CYTOPLASM  The cytoplasm is the gel-like substance that fills the entire cell.  This is where all cell activities take place.  Main ingredient: WATER

11
MITOCHONDRIA  Inside a chemical reaction takes place to release energy for the cell to use. This process is called CELLULAR RESPIRATION Takes in O 2 and sugar; Releases energy, CO 2 and H 2 O  Energy is released by breaking down food  AKA the powerhouse b/c it releases energy from food.

19
VACUOLES  Does the exact same thing in plant cells that it does in animal cells…only MUCH BIGGER.

20
All organisms need Carbon, but how do they get it?

21
All organisms need Carbon to do their life activities  Plants absorb carbon out of the air  Animals get carbon when they eat plants or other animals  Animals release carbon into the air when they breath

22
All organisms need Carbon to do their life activities  Bacteria and Fungi get carbon from waste and dead organisms and put it into the air  Anything burning also puts carbon back into the air for the plants to use and start the cycle all over again  This cycle is call the Carbon Cycle
